    My full suspension Dahon folding bike BBS02 conversion:


      My BBS02 on a 18" 2009 Muddy Fox Xernt:
      Full Build to be added soon, but suffice to say this was the smoothest conversion of a BBS02 for me yet! Everything just bolted right on, nothing more than a thin washer from some old caliper brake pads on the two mounting bolts, and the 52V 11.6AH Carbon Shark (kit & battery from Luna) fit perfectly, just added some low profile M5 x 0.8 waterbottle screws w/ another set of washers from old brake pads. : )

        Like the Cannondale, and have thought of building up a quick 1. How has it worked out for you?

          Its been a great bike. Very easy conversion. I'd recommend it.

        Raleigh Retro Cruiser, w/ bbs02


          This is my second build. BBS02 installed on a 2002 Ladies Trek Navigator 300. Frame size is 16.5". BB is 73mm, Battery mounted on Bontrager cargo rack. The installation was pretty standard with no issues. My wife loves the bike as we live near the top of a steep hill.

            2017 Motobecane Lurch. 100mm BBSHD with a 13.5Ah Shark. This is the smallest frame they sell. A 14" frame is just barely big enough to shoehorn a Shark pack i nto. I had some clearance issues though. The chain stays are extra short to bring the rear wheel as close as possible to the seat post, providing quicker turning and off-road h andling. If I had to do it again, I'd simply cut the chain stays off the BB and weld in a spacer to give enough room for the BBSHD to clear. The frame is 4130 CrMo steel, so I can weld on it without significantly weakening the frame. Yes it does weaken the frame some, but not like it would an aluminum frame. Here are some pics of the work, and the finished product. I know this is a lot of pics, but I didn't just bolt it on and go. I even used 5 bolts to hold on the battery.

              What seat is that? How do you like it? I'm considering trying the ISM Sport or Touring soon with my S-T Thudbuster.

              It's an Easy Seat II. I wanted a comfortable seat which was noseless, so when I got bounced off and landed back on it, I wouldn't get goosed by it.

            I try to keep these values in mind, and take it easy on the battery (keep the motor RPM up).
            Are you pedaling at 120 rpm or just using that for planning? coasting and letting the motor work? I could see pedaling at 100 rpm, but 120 would get old pretty quickly on a longer commute

                I picked up this Sears, fat tire “Iron Horse” on Craigs List for $200. Steel frame with 26 inch wheels. The bike needed nothing for the conversion except a Bafang BBSHD kit. Removed the front derailleur and shifter leaving me with 7 gears. Using a half-twist Bafang throttle on the left side, DPC-10 display, 7 speed twist shifter on the right and a 52V 13.5AH Panasonic Dolphin battery. I installed a Luna aluminum 42” chain ring. It is great to ride on single tracks and hits top speed of 30 mph in 7th gear on the street. I've gotten 24 miles plus in PAS level 1 with light peddling. Total cost was under $1200 for the bike, battery, chain ring and motor kit. No other modifications. Was not too difficult to adapt this kit to this bike.
                I REALLY enjoy this ride!!!!! ( I’m 63yrs old )

                    Hi all,
                    I am new here and this is my build:
                    bike: specilized stumperjumper fsr 2007, al frame
                    motor: bbs02 750W
                    battery: 48V 13Ah, 65cells LG M26
                    battery is in large shark case, it is in backpack for now as it cant fit on downtube. I ordered smaller shark casing 52cells, will go without cell holders and place 56 cells 14s4p, so it will be 52V 10.6Ah and it will fit on downtube.

                    last picture shows how I solve power cut off, basiclly it is power on demand, this is momentary switch taken from brake lever that came with kit, this is working great as I ride this bike mostly on trails. I wil eventually go for palmrest handles and integrate this switch better in handle or change switch for some smaller one. This works simple, when holding switch pressed you have power, as soon as you release it you have power cutoff.

                    Update: 3.9.2017.
                    I finally received smaller shark case (52 cells), as I had case with 65 cells. I swap batteries this weekend into smaller casing (without cells holders, so I fit 56 cells 14s4p) and install 52v battery on down tube. it fit perfectly, here is picture.

                    I had to make modification on cradle to bolt it onto downtube, but nothing major.

                    Finally I made saddle bag battery 14s2p using samsung 30q cells. Battery is just great, it fits in topeak medium bag.

                      Hello from France,

                      I have a old Giant Trance 2 of 2007 and I need your advice to install a kit Bafang bbs01 350W 36V.
                      It seem that some people of you have been successful install this kit.

                      My questions :

                      Do you think that the distance between the ground and the motor is a problem during mountain bike practice.
                      And I need your advice about the integration of the battery with this cycle. If you have some link I will be very happy

                      Sorry for my mistake language :)

                      Kind regards

                        The ground clearance will be less. Have you made up a battery template to see if a shark pack will fit.


                      Hi all, just wanted to let you know that I am about to start the build with BBS02B on a 2011 Specialized Epic Fsr Comp, in to an electric hybrid road and light trekking project, I got the bike, adapter, new rims , road tyres, pedals, arms etc etc and waiting for delivery of the motor kit, this bike has a 46x73mm PF30 BB shell, (but beware, only from 2011 confirmed, 2009/2010 ones have an incompatible bracket which will need custom machined parts, still investigating post-2011), with the PF30 to BSD adapter everything should be fine. If my calculations are correct (fingers crossed) the engine should fit with no particular modification but I will confirm once its here. I might have issues to fit the battery in the frame unless i un-build it (unfortunately medium frame, only one i could find, in the large version should be fine) as its an Hailong(Shark)pack, 48v 17AH with Panasonic/LG cells, which is 110mm tall, the lower AH are only 90mm which would fit in the frame below the shock. I will see if i can hook it below the main tube or even vertically, under the seat. I will post pictures soon.
                      The bike is a beauty to look at, very light, very good tech on it, can be bought for decent prices and its got a carbon version which weights under 10Kg (!!!) which will be my next attempt if this is successful, carbon can be nasty...
                      It deserves a try, just look at it!! Click image for larger version  Name:	906-906-EPIC-FSR-Comp-2011.jpg Views:	1 Size:	281.3 KB ID:	46393



                      I rather wait 20 days and save nearly 200$ compared to shark pack.



                      EDIT: PLEASE NOTE, After inspecting the bike I discovered that is has a simple threaded BB shell 73 x 42 like below, which makes things easier but confuses me as in specialized tech manuals its stated that this bike should have different brackets. Anyway better like that..Build started.

                          Got the gear, i opened the case to check the cells and they are Panasonic. I have a colleague that bought the same pack with a 750 bafang he did 3500km and still working perfectly. So Im fine with it:) Im about to start post about the build today anyway.
